Abstract

A computer system with two operating systems is disclosed. When the computer system is starting, the BIOS is loaded in memory for system test. Then the first operating system is selectively loaded in the memory for running the applications stored in the memory, or the second operating system stored in hard disk is selectively loaded in the memory for running it.

Description

Computer system with two operating systems
The invention provides a kind of computer system, a kind of computer system with two operating systems particularly is provided, the operating system in two operating systems is to be stored in the storer, to shorten the time of start.
In the epoch of this information prosperity, computing machine has become indispensable instrument in the daily life, in computer system, because the operating system of windowing develops very fastly, the function of operating system constantly increases, and therefore the time of open operation system becomes rather tediously long in start process, yet in the scientific and technological epoch of electronization, the user sometimes only wants to check data such as address list or calendar, but must wait one period very long on time, thereby very inconvenient.
See also Fig. 1, Fig. 1 is the functional block diagram of known computer systems 10.Computer system 10 includes a processor 20 and is used for executive routine, one primary memory 30 is used for depositing processor 20 employed program and data, one storer 40 is used for depositing a ROM-BIOS (BIOS-basic input/output system) 42, one hard disk 60 is used for depositing an operating system (operating system) 62, application program 64 and data 66, one display device 80 and an input media 90 and is used for allowing user's manipulation operation system 62 and application program 64.
When computer system 10 starts, pack into earlier primary memory 30 and carry out a system testing function of ROM-BIOS 42, then computer system 10 just can will be stored in operating systems 62 in the hard disk 60 primary memory 30 of packing into, to open and to carry out the application program 64 that is stored in the hard disk 60, in this process, because the processing speed of hard disk 60 is the storer of other kinds relatively, as ROM (read-only memory) (ROM), random-access memory (ram), it is slow that flash memories (flash) etc. are wanted, and present operating system 62 is windowing and function is very powerful, therefore pack into very tediously long of time of primary memory 30, for the user, wait for that the time of computer system 10 starts is too permanent.
Therefore fundamental purpose of the present invention provides a kind of computer system with two operating systems, and wherein an operating system is to be stored in the storer, to address the above problem.
In order to realize purpose of the present invention, a kind of computer system is provided, this computer system includes:
One processor is used for executive routine;
One primary memory is used for depositing employed program of this processor and data;
One storer is used for depositing a ROM-BIOS, one first operating system, and at least one application program; And
One hard disk is used for depositing one second operating system;
Wherein this computer system is when start, earlier this ROM-BIOS is packed into this primary memory to carry out a system testing function, thereafter this computer system this first operating system that can select to be stored in this storer is packed this primary memory into to open and to carry out the application program that is stored in this storer, or select to be stored in this second operating system in this hard disk and pack this primary memory into carrying out this second operating system, and this first operating system only can be carried out the application program that is stored in this storer.
Aforementioned calculation machine of the present invention system also includes one and is used for selecting to open the switch of this first or second operating system.
Aforementioned calculation machine of the present invention system also includes a display device and an input media that is used for display screen, and the user can utilize this display device and input media to control this application program.
Fig. 1 is the functional block diagram of known computer systems.
Fig. 2 is the functional block diagram of computer system of the present invention.
See also Fig. 2, Fig. 2 is the functional block diagram of computer system 110 of the present invention.Computer system 110 includes a processor 120 and is used for executive routine, one primary memory 130 is used for depositing processor 120 employed program and data, one hard disk 160 is used for depositing one second operating system 162, and one storer 140 be used for depositing a ROM-BIOS (BIOS-basicinput/output system) 142, one first operating system 144, and at least one application program 146.
Computer system 110 is when start, ROM-BIOS 142 can be packed primary memory 130 earlier into to carry out a system testing function, thereafter computer system 110 first operating systems 144 that can select to be stored in the storer 140 are packed primary memory 130 into to open and to carry out the application program 146 that is stored in the storer 140, or select to be stored in second operating systems 162 in the hard disk 160 and pack primary memory 130 into carrying out second operating system 162, and first operating system 144 only can be carried out the application program 146 that is stored in the storer 140.
As shown in Figure 2, storer 140 can be substituted by ROM (read-only memory), certainly also can be flash memory 150, be used for storing outside ROM-BIOS 142, first operating system 144 and the application program, also can be used to the application program 146 needed data (data) 152 in the memory 140 (or ROM (read-only memory) or flash memory 150).When second operating system 162 of computer system 110 in carrying out hard disk 160, second operating system 162 can write data 152 in the flash memory 150, or the data 152 in the flash memory 150 are read.
Computer system 110 includes a switch 170 in addition, be used for select opening first operating system 144 in the storer 140 (being ROM (read-only memory) or flash memory 150) or second operating system 162 in the hard disk 160, one display device 180 is used for display screen, an and input media 190, the user can utilize display device 180 and input media 190 to control the interior application program 146 of storer 140 (being ROM (read-only memory) or flash memory 150), and it can be a calendar (calendar), telephone directory (phone book), p.m.entry (memorandum) or other application program.
Compare with known computer systems, there is first operating system 144 in the storer 140 of computer system 110 of the present invention (being ROM (read-only memory) or flash memory 150), therefore work as the user and only will read some master datas, the user can open computer system 110 apace by opening first operating system 144, and does not need to wait for one tediously long period.
The above only is preferred embodiment of the present invention, and all any variation and modifications of doing according to claim of the present invention all belong to the covering scope of patent of the present invention.
